Although it's far from a confirmation that the reboots have been fixed in 4.2.2, I just updated 11 apps while browsing different tabs in Chrome, and the N10 handled it fine and didn't reboot. This is something that I've noticed cause a reboot on multiple occasions in the past. Hopefully it's a good sign.

Nexus 10 user here that has at least daily freezes or reboots on 4.2.1, even with location services disabled and completely abandoning Chrome.

I got the 4.2.2 OTA and installed it today. I am going to keep location services off and keep using Firefox instead of Chrome so the use case remains the same for a week or so. I will make sure to update with my experience on 4.2.2.

If all goes well, I will turn on location services and begin using Chrome as well and I will check back in after some time with that configuration.

There was some postings from Google developer(s) saying that they found a cause of the Null Pointer Exception (NPE) errors that were causing the random reboots. The fix(es) are applied in Android v4.2.2 release. Let's hope it really catches all the causes of the random reboots.

They say it is fixed. Location manager was misbehaving and causing activity manager parcel() method to get NPE errors. So according to this, it seems the location manager was at least the culprit of many random reboots. (But in my take, other misbehaving apps caused reboots too). But they also said they added the catching of errors in the activity manager so that it will not reboot on NPE I think...
I hope it is truly fixed now.

I've been running the 4.2.2 update since yesterday and i have around 10hrs use. Battery is greatly improved, doesn't get as warm as it did before while just using falcon, g+, chrome beta. Since the update I've had location on and so far no reboots.

Hate to be the bearer of bad news, but while I haven't had any reboots - my N10 just froze up on me while in the Play Store app, had to force reboot.
Just updated to 4.2.2 this morning. Not a good sign.

My one freeze since updating to 4.2.2 has been in the Play Store app as well. Or more precisely, when exiting the app. Hasn't locked up yet in Chrome though.

I just experienced a freeze and reboot on my Nexus 10 running 4.2.2 immediately after enabling WiFi. The previous uptime was 1 day 18 hours, which is better than my average (but not my max) under 4.2.1.
